Compare the Analysis and Design by Limit State Method of G+1 RCC Bunglow by using STAAD Pro and Manual Calculation

Abstract

In today’s world, the importance of structural engineering is increasing day by day. Structural Engineer is not only responsible for designing a durable, serviceable structure but it’s more important to design an economic structure. With rising construction costs and limited resources, designing a cost-effective building is essential. The process of manual analysis and design of RCC structure becomes more complex for heavy structure so the use of software’s is necessary, for the effective use the theoretical concepts of analysis and design must be known. Similarly, the knowledge of IS codes is also mandatory. So for the detailed study this project includes the comparative study of analysis and design of G+1 RCC Bungalow by manual calculation and by using STAAD Pro software. We at initial stage manually designed a G+1 RCC Bungalow by limit state methods using IS Codes, SP 15 Code and after that we have designed the same Bungalow by using a STAAD Pro software and finally compared the results.

Introduction

With growing population, there is a significant rise in residential, commercial, and infrastructure construction, putting pressure on structural engineers to design safe, durable, and economical structures. Advances in technology have introduced software tools like STAAD Pro and E-Tabs that simplify structural analysis and design.

This report focuses on analyzing and designing a G+1 RCC bungalow using the Limit State Method, comparing manual calculations with STAAD Pro results. The aim is to study RCC structure design, learn STAAD Pro software, and compare both approaches for elements like slabs, beams, columns, and footings.

The project scope can extend to different load combinations including dead, live, and wind loads.

Detailed manual calculations are presented for various structural components:

• Slabs: Two-way slabs analyzed for load, moments, reinforcement, and spacing.

• Beams: Load, bending moments, shear, and reinforcement design including shear reinforcements are calculated.

• Columns: Load calculations, eccentricities, moments, reinforcement, and lateral ties are designed according to relevant codes.

The comparative results highlight differences in load, moments, reactions, and reinforcement detailing between manual and STAAD Pro methods.

Conclusion

Thus, we can say from the comparative study for a given G+1 RCC bungalow using STAAD Pro and manual calculation steel quantity is reduced for the structural element which is as follows: - 1) For slab percentage of steel is reduced by 0. 67% 2) For beam percentage of steel is reduced by 0.62% 3) For column percentage of steel is reduced by 0.69% 4) For footing percentage of steel is reduced by 0.11% 5) For footing volume of concrete is reduced by 46% From above conclusion it proves that STAAD Pro gives optimize analysis and design of given structure. Due to optimize analysis and design of STAAD Pro economy can be achieved. Through this project we studied manual and software analysis and design by limit state method of RCC Structure in detail.
